Struct coset::CoseSignBuilder

pub struct CoseSignBuilder(_);

Builder for CoseSign objects.

Implementations

impl CoseSignBuilder

pub fn new() -> Self

Constructor for builder.

pub fn build(self) -> CoseSign

Build the completed object.

pub fn protected(self, hdr: Header) -> Self

Set the associated field.

pub fn unprotected(self, unprotected: Header) -> Self

Set the associated field.

pub fn payload(self, payload: Vec<u8>) -> Self

Set the associated field.

pub fn add_signature(self, sig: CoseSignature) -> Self

Add a signature value.

pub fn add_created_signature<F>( self, sig: CoseSignature, aad: &[u8], signer: F ) -> Selfwhere F: FnOnce(&[u8]) -> Vec<u8>,

Calculate the signature value, using signer to generate the signature bytes that will be used to complete sig. Any protected header values should be set before using this method.

pub fn add_detached_signature<F>( self, sig: CoseSignature, payload: &[u8], aad: &[u8], signer: F ) -> Selfwhere F: FnOnce(&[u8]) -> Vec<u8>,

Calculate the signature value for a detached payload, using signer to generate the signature bytes that will be used to complete sig. Any protected header values should be set before using this method.

Panics

This method will panic if self.payload.is_some().

pub fn try_add_created_signature<F, E>( self, sig: CoseSignature, aad: &[u8], signer: F ) -> Result<Self, E>where F: FnOnce(&[u8]) -> Result<Vec<u8>, E>,

Calculate the signature value, using signer to generate the signature bytes that will be used to complete sig. Any protected header values should be set before using this method.

pub fn try_add_detached_signature<F, E>( self, sig: CoseSignature, payload: &[u8], aad: &[u8], signer: F ) -> Result<Self, E>where F: FnOnce(&[u8]) -> Result<Vec<u8>, E>,

Calculate the signature value for a detached payload, using signer to generate the signature bytes that will be used to complete sig. Any protected header values should be set before using this method.

Panics

This method will panic if self.payload.is_some().

Trait Implementations

impl Debug for CoseSignBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CoseSignBuilder

fn default() -> CoseSignBuilder

Returns the “default value” for a type.
